I don't look on here more than every few weeks anymore. Just saw this. Been trying to contribute more lately. Figured I would say that anyone who asks this question will need 2-4 hours for the Spartan install to do it properly. Not something you rush at all.
If you do not know the axle disassembly and reassembly off the top of your head enough to answer this question it will take a while. It can be done in an hour if you fly through knowing exactly what your going to be doing before you get to each step as you go. Stuff like what size six point sockets for the unit bearings, our spanner socket for the spindles on a 44. How long inner seals take to replace if you find a problem with one. (PIA no matter what) Also, some carriers require the ring is pulled off the carrier to get any lunchbox in. I even had this issue with a 44 front with 354 gears. So in no way thick cut or anything, but I couldn't fit a 30 spline Spartan past the ring gear no matter what I tried. With some axles you can shove the Spartan in without pulling the carrier at all. When you run into the problem I just described though, you have to pull the carrier. I also had this issue with a dana 30 that was a stock 410 ratio in a 4 banger, so no thick gears there either.
Whenever doing axle work, take the amount of time you think it will take you, double that, then add a little bit for good measure. That's how much time you should have when working with differentials. You do not have room for error. I didn't used to follow that time rule myself like I should have. After countless jeeps through my shop, I quote all work using that rule, and also give myself the same amount of time for the stuff I do. Before I had my own shop, I more than one had to leave a jeep or two overnight somewhere 30-45 min from home just so I could return and do it the next day.
One other thing here. After dealing with a lot of 44 axles, I suggest changing the unit bearing style to the more serviceable spindle 44 style whenever possible. Basically, knuckle out upgrade. Especially if you're going to high steer. It is a much stronger assembly for one of the most commonly broken parts. I used to go through unit bearings so regularly I kept a spare in my jeep at all times for trail fixes.
Hope this info helps some of you who look at this later on from a Google result to avoid headaches if doing this work yourself. It's definitely within the realm of shade tree mechanics. Just not something you take apart in a rush and throw together because of time constraints.
